I don't think we care about false-but-dont-care-much. Pack-objects just needs to know whether the bitmaps are the user's expressed intention, or just something that it should do if it's convenient. I'll see if I can work up a patch to demonstrate. > On this general topic a *soft* poke about relying to > https://public-inbox.org/git/8736lnxlig.fsf@xxxxxxxxxxxxxxxxxxx/ if you > have time.

I just left a reply, though I think most of the discussion there is about the actual pruning-corruption race. I'm totally on board with the idea of an "unreachable pack", but AFAIK nobody has produced any patches yet. > More generally we're really straining the gc.log pass-along-a-message > facility. I definitely agree with that. :) -Peff
